ANDREW BEYRLE, OF LOS ANGELES, CALIFORNIA.

MACHINE FOR COVERING STRIPS OF WOOD WITH METAL.

Application filed August 16, 1909.

To all whom it may concern:

Be it known that I, ANDREW BEYRLE, la citizen of the United States,residing in the city of Los Angeles, county of Los Angeles, State ofCalifornia, have invented new and useful Improvements in Machines forCovering Strips of TNood with Metal, of which the following is aspecification.

My invention relates to improvements in machines for covering strips ofwood with metal in which the dies for forming and pressing the metalupon the wood may be stationary and the wood and metal pushed throughthe dies or the wood and metal for the casing may be stationary and thedies for forming and pressing the metal upon the wood may be movable.

rlhe object thereof is to provide a machine of simple construction forthat purpose, and in which the forming dies have a large range ofadjustment and consist of separable parts which can be quickly andefficiently adjusted in the machine I accomplish this object by themachine described herein and illustrated in the accompanying drawings,in which- Figure 1 is a side elevation partly in section of my improvedmachine. Fig. 2 is a plan of the parts shown in Fig. 1. Fig. 3 is asect-ion on the line 3 3 of Fig. 5, with the holding mechanism above thedies shown, the supporting legs being broken o. The die holding thetable being shown partly in elevation and partly broken away. Fig. i isa section on the line 4 4: of Fig. 1. F ig. 5 is an enlarged plan partlyin section of the forming dies with a piece of wood and metal partiallypassed therethrough, a portion of the forming mechanism being omittedfor clearness of illustration.

In the drawings 10 is the main frame of the machine and is provided withlegs 11. At one end of the frame is mounted a train of wheels 12. Onshaft 13 of this train of wheels is power pulley 14 to which motion isapplied by means of a belt not shown. Shaft 15 of this train of gearscarries a sprocket wheel 1G on which is mounted a sprocket chain 17. Theother end of the sprocket chain passes around the idler sprocket wheel18 which is mounted on shaft 19. Shaft 19 is mounted in adjustable bear-Spcccaton of Letters Patent.

ings, one of which 20 is shown in Fig. 1. rhese bearings are adjusted bymeans of screws 21, so as to take up any slack of the chain that may beobjectionable in the operation of the machine. A chain shelf 22 forms asupport for the upper portion of the sprocket chain, and also securesthe side rails of the main frame together. Upon the top of the siderails of the main frame are the adjustable guide rails 23. The opposededges of these guide rails are wedge shape as best shown in Figs. 3 and4. 24 is the bed plate of the die frame, which is provided with V-shapedgrooves 25 in the edges of the lower member thereof, into which arereceived the opposing edges of the guide rails. Near one end of the bedplate is a slot 26 in which is pivotally mounted draw bar 27, which hasa head 27'h1 that is adapted to drop into the links of the sprocketchain and be caught by the sprocket chain when the same is in motion,whereby motion is imparted to the bed plate in whichever direction thechain ris traveling. Should the operator fail to stop the machine beforethe draw bar reaches the sprocket wheels the teeth thereof would pushthe draw bar head out of the links of the chain, thereby stopping themovement of the bed plate. Upon the central member 24L of the die frameare secured bars 2S, which form the top member of the die frame. Thesebars are spaced apart, thereby forming channels 32 between them toreceive bolts 29, 30 and 31. Adjacent to these channels, bars 28 arenotched in their upper surface to form a broadenedA portion in which thelower portions of the dies 34E are received to keep them from skewing.The Shanks of bolts 29, 30 and 31 where they pass through channels 32are square so that they will not turn in the channels. Immediately belowchannels 32 are channels 33 which run transversely across the top of thecentral member of the die frame, thereby providing clearance for theheads of bolts 29, 30 and 31. Bolts 29 are used for securing dies 34 inplace on the frame. These bolts are long enough to pass through holes inthe dies and extend a little above them, so that nuts 35 can be screwedupon the bolts and leave a little play for lthe head of the bolt whenpassed in the slot between the die holders. There are preferably two ofthese bolts for each die, and when the die is properly positioned theyare screwed down so as to hold the die firmly upon the bed plate. Asshown in the drawings, I prefer to use a plurality of dies to form themetal up gradually to the contiguration of the wood. The die nearest theunformed metal V:making the first turn in the metal as shown at A inFig. 5. The next die will turn the metal a little farther as shown at B,the next die will turn it a little farther as shown atC, while the lastdie will finish the turning of the metal as shown at D. But a greater orless number of dies will be used, depending upon the character of thework. In the drawings I have shown a piece of wood, in which one faceand a portion of the edges are covered with metal, but it will beunderstood that the four surfaces of the wood can be covered by usingappropriate dies.

Bolts 30 are longer than the die bolts and pass through the ends of thespring pressure bars 36. There is preferably one of these springpressure bars for each pair of dies, and they may be made of resilientwood or steel. Mounted on bolts 30 above these pressure bars, when agreater resiliency is desired than can be obtained in the bar itself,are rubber springs 37, which are held in place by nuts 3S. Coil springscan be used in place of rubber. Nuts 39 may be placed on bolts 30 belowthe pressure bars to prevent too great a disarrangement when the barsare not in use, and to hold the bars at an elevation so that they willpass above friction bar 40, which rests upon the piece of wood 41 thatis covered by the strip of metal 42. It will be understood that nuts 38and 39 will be adjusted to hold the piece of wood being-covered in itsproper position. Friction bar 40 is secured to the brace yoke 48 toprevent any longitudinal movement of the dies as they are being forcedalong. This brace yoke is secured in the die frame in the same mannerthat the dies are secured therein. 44 is an abutment yoke which issecured to the main franie. The vertical portions of this yoke are wideenough apart for the die frame to pass between them, and the transverseor top member thereof is high enough to permit the passage of the dieframe and the several parts secured thereto when the machine is inoperation. In the abutment yoke is pivotally mounted the abutment bar 45which carries on its free end a removable abutment shoe 46. The shank ofthe abutment shoe is bifurcated as best shown in Fig. l, and straddles aholding pin 47 which passes through the free end of the abutment bar,thereby providing an easy means of securing different sized abutmentshoes upon the end of the abutment bar, as in some cases a narrowabutment shoe will be required, while in other cases a broader abutmentshoe will be required. Set screws 48 and 49 mounted in lugs 50 securedto the abutment yoke provide means for adjusting the height of the freeend of the abutment bar to properly position the shoe for use on thewood of thicker or thinner dimensions.

In the operation of my machine the wood to be covered or faced withmetal and the metal for the covering or facing of the same are securedtogether in any appropriate manner at that end which would be firstreached by the dies, and is then laid upon metal guide 52 which issecured upon the die holder bars, with the other end of the wood restingagainst the abutment shoe, as shown in Figs. l and 2. Guide holders 51are then securedV at one side of the wood and metal in the same mannerthat t-he dies are secured. There are as many of these guide holders asmay be necessary to prevent t-he wood from springing or buckling. Theseguide holders have a top portion that projects over the wood and thelower portion is cut out so as to provide clearance for the metal andthe metal guide as best shown in Fig'. 4. The metal guide 52 is placedbeneath the metal strip that is used for facing or incasing the wood andhas edges partly upturned as shown in Figs. 2 and 4, between which themetal used in casing has a loose fit. At suitable distances apart theportion of the edges of the metal guide 52 which are not upturned aresecured to the die frame by clips 53, as best shown in Fig. 2, so thatit will travel with the die frame. These slips are secured in the dieframe in the same manner as the dies. Guide holders 51, after beingadjusted for running a certain kind of material are allowed to remain intheir position in the die frame. A movable guide holder 54 is providedfor the other side of the wood. The movable guide holder is connected bylink bars 55 with a base block 56, which base block is secured in thedie frame by bolts in the same manner that the dies are secured, Anoperating lever 57 is pivotally secured to the base block and to themovable guide holder so that t-he guide holder may be quickly thrownaway from engagement with the wood to permit the removal of the wood orto be thrown back against the wood to hold it in place. The necessaryforming dies are also secured in the frame together with the pressurebars and friction bar and other necessary parts as hereinbeforedescribed, and the die frame is connected up by the draw bar to thesprocket chain. Power is then applied to the train of Wheels to causethe travel of the die frame toward the same, thereby causing the dies topass along and form the metal for the casing upon the Wood. By thisconstruction the dies are draivn over the Wood and metal until the firstdie almost reaches the abutment shoe When the motion of the sprocketchain is reversed and the die frame carrying the dies and the cased Woodis returned back to the starting point. Another piece of metal and Woodis then placed in the machine as before described and motion is impartedto move the dies toward the abutment shoe, thereby ejecting the firstpiece ot Wood and moving the dies over the other piece of Wood as beforedescribed. The operation is repeated until all the Wood is covered, thelast piece being pushed out of the dies by means of a block placedbetween the abutment shoe and the end of the Wood that is being eased.

In this construction it will be observed that the die holder barsoperate as the bottom side of a die. It Will also be observed that inthis construction the side members of the die are adjustable so thatWood ot any Width iv iere the side is of the same contiguration can becased on the side by the same sectional side dies. It Will also beobserved that the top 'friction bar and the top spring bars may operateto form the metal on the top in the same manner that the top portion ofthe die used in the ordinary pulling machine operates. It will also benoted that these die holder bars and sectional dies adjustably held insuch die holders are equally applicable to the machine described.. inLetters Patent 887,995, issued to me May 19th, 1908, but in suchmachines the die holders would be stationary, Whereas in the presentmachine they are movable with the die frame.

I am aivare that die frames in which revoluble diesl are mounted haveheretofore been used. In the use of said dies and frames, it there areany inequalities in the metal, the roller dies roll over the same. Bythe use ot nonrevoluble dies all inequalities in the metal are stretchedout of the same, and vthe metal is stretched into skin tight contactWith the Wood. I do not therefore broadly claim a movable die tramehaving dies therein.
